The SVS II Deluxe Valve Refacer is the most accurate Valve Refacer made today.
.0005 accuracy for standard chuck and
.0002 accuracy for high-performance chuck. The Industry's Best.
The Kwik-Way CenterLine Chuck is what makes the SVS II Valve Refacer a cut above all the rest. Other Valve Refacers use Chucks, referred to as "center less". These use rollers to grip the valve stem while the Kwik-way Chuck uses two sets of independent balls that grip the stem at two very distinct points. The advantage being, if you have a center less chuck and you're trying to grind an in-service valve, if there is any out-of-round on the valve stem, that out-of-round is transferred from the rollers on the center less chuck to the valve face. So your face run out will be no better than your stem run-out.
With the Kwik-way Chuck, since it uses two sets of balls that capture the valve in the wear area of the stem, will automatically re-centerline the valve. What that means is when we grind the valve, the face will come out true to the center line of the stem that actually rides in the valve guide.
In other words, if there is some wear on the stem surface the Kwik-Way Chuck is going to compensate for that wear in such a way that the resulting ground valve face is perfectly centered when the valve is back in the engine.
Some valve manufacturers design their valves with a tapered stem. Because of the unique way The Kwik-Way Chuck grabs the valve stem, taper has no influence on the precision of the positioning of the valve in the chuck. Other Valve Refacer Chucks may cause the valve to tilt in the chuck. Without a way to compensate for valve stem taper, you cannot reface the valve with the same amount of accuracy as with a Kwik-Way machine.
The Kwik-Way Chuck is air activated. You simply push a button that will release the two sets of balls and allow you to insert the valve. You will have a range of 4mm to 14.3mm with the standard or high perfermance valve chuck.
Another type if chuck used on other machines is a collet chuck. To give you the range of 4mm to 14.3mm you would need at least 5 or as many as 9 different collets to cover that range. As you now know, with the SVS II, there is no change over required for various stem diameters. And as you change collets there can be problems with repeatability because you can put the collet in the receiver with dirt or grit between the receiver and the collet. In that case, you will get inaccuracy. Also, if you have a tapered valve, the collet will not compress to the same tension at both points so again with a collet chuck and a tapered valve you get inaccuracy.
The same is true with an out-of-round valve. Because the collet wants to compress uniformly around the circumference of the stem. The bottom line is that the other chucks grab the valve stem using a greater amount of the valve surface, which can be a problem if there are any irregularities in that valve.
The SVS II D comes standard with tip grinding and rocker grinding capability. It can also chamfer tips. There are no optional accessories necessary to perform these functions. Unlike with other machines where you will find that you have to purchase additional accessories in order to do these other jobs or to get the same amount of valve stem diameter range as the Kwik-Way SVS II Deluxe Valve Refacer.
You can transition from valve refacing to tip grinding or rocker arm grinding operations for shaft mounted types of rockers in less than minutes. And it's all standard with the machine.
Kwik-Way Valve Grinding Wheels are very reasonably priced. Our wheels are formulated and manufactured by one of the largest manufacturers of grinding wheels in the world and they are designed specifically for our machines. Kwik-Way offers various types of wheels. We have general purpose, finishing, titanium, and hard alloy, so no matter what type of material comes into your shop you are going to be able to handle it.
To change and redress a wheel on the SVS II Deluxe machine only takes about 2 minutes. We find that our general purpose wheel is sufficient for most operations, but of course, if you get a high performance valve or titanium alloy valve, you will need to change to a different grinding wheel.
We also offer a Valve Cabinet designed specifically for the SVS II D machine. The footprint of the cabinet allows for a good ergonomic workstation. With excellent storage below in the cabinet. We find that some people already have areas in their shop that they have a station designed for and as long as the bench is adequate to support the weight of the machine it will work fine.
The SVS II Deluxe Valve Refacer is sold all over the world. Kwik-Way is by far the largest provider of valve equipment in the entire world. We have various voltages available and also various chuck capacities.
The SVS II Deluxe Valve Refacer comes with a unique warranty we call the 5-2-1 warranty. The base of the unit is warranted for 5 years, all other parts for 2 years and the first year everything is warranted, parts, labor and electrics. We also have a exclusive 3 year limited warranty on the Chuck. We warrant it against loss of accuracy.
Most all Funny and Top Fuel Race Teams are using a Kwik-Way Valve Machine. If you look at their trailers you will find they have Kwik-Way valve grinders on them. The only equipment they trust for regrinding high performance engine valves is a Kwik-Way machine. And while many companies will give their equipment to these types of organizations in exchange for the promotional value, Kwik-Way does not. So if a high performance shop is using a Kwik-Way machine it is by their choice and they paid to have that machine.
